Slate Tablet

Inscribed by its contributor with the statement "Your new information technology may become obsolete". According to Wikipedia, the use of writing slates dates back to the 14th century, but became the primary tool in the classroom for students in the 1800s century and remained so until the 1930s, when pencil and paper became more common.

Mechanical Calculator

The Monroe Calculator Company, founded in 1912, started out making mechanical adding machines. Electromechanical calculators, like this one, were produced through the 1960s and 1970s. This one is probably from the late 1950s and cost $595 when new. It was probably used by ecologists to calculate life tables.

IBM PC

The IBM PC is perhaps the most iconic computer of all time, symbolizing the transformation from when computers moved from the backroom and office to the home. Purchased in 1983 for $4500, this computer had an 8088 processor (around 5 Mhz), 640K of RAM, and 2 160kb floppy drives.

TRS-80 Model 100

The Model 100 version of the classic TRS-80 set the standard for mobile computing for a generation. It was still in service -- and in demand -- 20 years later for journalists and scientists working in remote areas due to its ability to use retail batteries (D-cells) and communicate reliably through simple telephony. The Microsoft BASIC interpreter is reputed to be the last code that Bill Gates personally worked on.

NeXT Cube

After Steve Jobs left Apple, he started NeXT to build high-end workstations. Early models had neither a floppy nor a hard-drive and, instead, used an odd magneto-optical disk. NeXT was ultimately purchased by Apple and its operating system formed the basis of MacOS X. Sir Timothy Berners-Lee, the creator of the World Wild Web, used a NeXT computer which became the first web server.

Floppy Disks

Floppy disks, initially as 8-inch (200 mm) media and later in 5¼-inch (133 mm) and 3½-inch (90 mm) sizes, were a ubiquitous form of data storage and exchange from the mid-1970s well into the 2000s. (From Wikipedia)

EZ 135 and Zip Drive

As portable storage needs outgrew floppies, two companies fought for dominance in the removable storage market. Ultimately, the Iomega Zip Drive won over the Syquest EZ 135 but, in the end, flash storage displaced all of these technologies.
